AIM: The aim of this study was to determine the positional relationship between the crown contour and the pulp chamber as well as the morphological characteristics of the pulp chamber using micro-CT in order to plan, in restorations of deciduous maxillary second molars, reconstructions with a volumetric rendering programme.STUDY DESIGN: In total 16 deciduous maxillary second molar teeth (8 from boys, 8 from girls) were used. The positional relationship between crown contour and pulp chamber was three-dimensionally observed by micro-CT. Differences in sex, dentin thickness and pulp volumes were evaluated using chi-square and paired t-tests. Differences were considered significant when P < 0.05.RESULTS: Dentin thickness was found to be 2.8 mm ± 0.2, mesiobuccally 3.15 mm ± 0.2 distobuccally 3.8 ± 0.3, which was statistically significant (p ≤ 0.05). The pulp volume for boys was 77 mm³ ± 4, for girls 64 mm³ ± 5, with a statistical significance (p ≤ 0.05).CONCLUSIONS: General differences could play a role when planning a treatment for a child; however for both genders it should be noted that mesiobuccal pulp horn is most likely to get exposed during cavity preparation.
